Description

Technical Field

[0001] The utility model relates to a juice extracting mechanism and a juicer. Background Art

[0002] At present, with the continuous improvement of people's living standards, juicers have been widely popularized in people's daily lives. General juicers are divided into two types of layouts: horizontal and vertical. Both types of juicers include a juice cup, a screw propeller rotating inside the juice cup, and a motor driving the screw propeller to rotate. Among them, the juice cup and the screw propeller of the horizontal juicer are placed horizontally, and the upper side wall of the juice cup has an opening for feeding fruits or vegetables. The juice cup and the screw propeller of the vertical juicer are placed vertically. Both types of juicers use the cutting section of the screw propeller to cooperate with the inner wall of the juice cup to crush the fruit or vegetables, and then separate the juice and the residue at the grinding section of the screw propeller.

[0003] Whether it is a horizontal juicer or a vertical juicer, the rotating shaft of the cutting section and the rotating shaft of the grinding section are coaxial or parallel. Therefore, when cutting some long strips of food that are not easy to break, if the long strips of food are not cut into multiple sections, they are easy to be entangled in the cutting section of the spiral propeller, affecting the juice output rate and even causing the spiral propeller to get stuck and the motor to overload.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figures 1 to 5 The utility model provides a juice extraction mechanism, comprising: a juice extraction cup 100, wherein the juice extraction cup 100 has a feed channel 110 extending in a vertical direction and a juice extraction channel 120 extending in a horizontal direction, wherein the lower end of the feed channel 110 is communicated with the juice extraction channel 120, wherein a feed impeller 200 is rotatably disposed in the feed channel 110, wherein the rotating shaft of the feed impeller 200 is arranged in a vertical direction, wherein a screw propeller 300 is rotatably disposed in the juice extraction channel 120, wherein the rotating shaft of the screw propeller 300 is arranged along the central axis of the juice extraction channel 120 and is orthogonal to the rotating shaft of the feed impeller 200, wherein the feed impeller 200 and the screw propeller 300 are both connected to a rotary drive device to realize synchronous rotation.

[0032] When the juice extraction mechanism of the above structure is working, the long strips of food are first placed in the longitudinal feed channel 110 to be broken by the feed impeller 200, and then the food broken by the feed impeller 200 enters the horizontal juicing channel 120 to be further broken and ground by the screw propeller 300. Since the rotating shaft of the feed impeller 200 and the rotating shaft of the screw propeller 300 are orthogonal, the long strips of food will not be entangled on the feed impeller 200 and the screw propeller 300 and cause the problem of being unable to be broken, which is conducive to crushing the long strips of food to improve the juice yield and reduce the possibility of the screw propeller 300 getting stuck and the motor 433 being overloaded.

The lubricating oil precipitated from the sponge 620 can flow to the worm member 432 through the inner wall of the sleeve 630. It should be noted that the coating of lubricating oil between the worm member 432 and the worm wheel member 431 is conducive to smooth transmission. When lubricating oil needs to be added, the plug 610 can be removed from the housing 500, and then the sponge 620 can be extracted, and the sponge 620 can be soaked in lubricating oil and then reinstalled, which is very convenient to use.

It can be understood that the stirring blades 220 and the cutting blades 230 both blend or cut the food along the inner peripheral edge of the portion close to the juice cup 100. The main function of the stirring blades 220 is to chop and crush the food put into the feed channel 110, and the main function of the cutting blades 230 is to cooperate with the connecting port 160 to cut the chopped and crushed food.
